UPDATE: The Geomagnetic Storm has subsided over the past few hours. However, the solar wind remains energized and occasional pulses of activity are expected for another 24 hours. Region 1283, the responsible party back at the Sun, decayed today. The Geomagnetic Storm
A double-barreled hole has opened up in the sun’s atmosphere and it is spewing a split-stream of solar wind toward Earth. NASA’s Solar Dynamics Observatory captured this composite UV image of the double coronal hole on August 20th:Sky watchers should be alert for
Solar Activity continues at fairly low levels with only C-Class activity taking place in the past 24 hours. Sunspot 1271 is the largest visible area and it may pose a small threat for an M-Class event.Farside CME activity continues and you can view all of the action
A second M-Class flare, this time a M2.5 took place at 03:54 UTC Tuesday morning around Sunspot 1263. This is in addition to the earlier M3.5 flare which we reported yesterday. The first flare produced a small, but fast moving (2010 km/s) Coronal Mass Ejection…
The magnetic field of sunspot 1236 harbors energy for M-class solar flares. NOAA forecasters estimate a 25% chance of such an eruption during the next 24 hrs.
NASA’s Solar Dynamics Observatory is monitoring a hole in the sun’s atmosphere – a “coronal hole.” It is the dark region circled in this extreme ultraviolet image taken during the early hours of April 28th: Coronal holes are places where the sun’s magnetic field
For the past week, all eyes have been on the Earth-side of the sun, where sunspots 1158 and 1161-1162 have unleashed some of the strongest flares in years. Meanwhile, the farside of the Sun has been busy, too. Here is the movie from NASA's STEREO-B probe…
